Phlox divaricata 'London Grove Blue'
Wild Sweet William or London Grove Blue Phlox
A delightful spring blooming native for shade, it carpets the shady border with pale blue. A low growing carpet of fragrant blooms with burgundy winter foliage makes this sweet william most appealing. Woodland phlox will spread and fill in around bulbs or perennials that are late to emerge, like hosta. Bought at the London Grove Friends Meeting House plant sale.

Interesting Notes
An indespensible spring ephemeral for eastern shade gardeners. The plants loft clouds of 1 foot flowering stems with narrow pointed cauline leaves that die after blooming and in the summer spread low stems of more rounded, dark green foliage. They will usually begin to self-sow and create great drifts that blend well with other woodlanders in successional plantings. William Cullina, NEWFS Guide to WildflowersIf P. stolonifera hugs, P divaricata hovers. The blue woodland phlox is nearly twice as high (to the knee when in flower) and twice as sweet; its other name is wild sweet William. Plants will cover ground more slowly than P. stolonifera, but we're still talking a creeping mound. Though each of its petals is notched at the tip for a somewhat showier flower, what really undoes me about the long-blooming P. divaricata is what it makes of the color blue: icy, subtle, rich, or startling, depending on the selection. Out of flower, it doesn't have quite the foliage presence of P. stolonifera (it's not as dense a cover); its strength is not as a specimen but as a mingler, chatting its way across the woodland floor.

Growing and Maintenance Tips
P. divaricata needs bright shade with organic, moist, well-drained, rich soils. These slowly spreading stemmed flowers can be found in rich woods and along stream banks. Give good air circulation to reduce growth of powdery mildew. Benefits from occasional fertilization. May be propagated by terminal shoot or root cuttings. Cut back after first bloom to promote second round of growth. Makes an excellent addition to the perennial, naturalized area or rock garden.Characteristics & Attributes
